Description

Technical Field

[0001] The utility model belongs to the field of ore conveying equipment, and specifically relates to an ore conveying structure. Background Art

[0002] The mined ore is usually conveyed by a conveyor belt. To ensure the smooth transfer of ore from the upstream conveyor belt to the downstream conveyor belt, a transfer funnel is usually arranged between the two conveyor belts, so that the ore enters the lower conveyor belt after being buffered and collected by the funnel. Ore mining is usually carried out underground or in high mountains, and there is often a certain height difference between the conveyor belts. Moreover, the material conditions of the mined ore vary, such as particle size change, mud content change, moisture change, impurity change, particle diameter change, etc. Especially when large-diameter ore appears, when the ore enters the lower conveyor belt through the transfer funnel, the ore will impact the transfer funnel, causing the funnel to deform and be damaged. Even some large-diameter ore will rebound after hitting the transfer funnel and hit the conveyor belt at a relatively high speed, which has a great impact on the normal operation of the conveyor belt and may even roll off the conveyor belt, posing a safety hazard. Summary of the Invention

[0003] In order to overcome the problems existing in the background art, the utility model provides an ore conveying structure. By arranging a stepped ore-settling platform in the transfer funnel and a buffer platform at the rear end of the ore-settling platform, the impact of the ore on the transfer funnel can be effectively reduced, the impact speed of the ore can be alleviated and reduced, the stable operation of the conveyor belt can be ensured, and the safety hazard of ore conveying can be reduced.

[0004] To achieve the above object, the utility model is realized by the following technical solutions:

[0005] The ore conveying structure includes an upstream conveyor belt, a transfer funnel, and a downstream conveyor belt; the transfer funnel is arranged between the upstream conveyor belt and the downstream conveyor belt; a stepped ore-settling platform and a buffer platform are arranged in the transfer funnel; the stepped ore-settling platform is higher on the left and lower on the right; the buffer platform is arranged on the right side of the stepped ore-settling platform; a main blanking channel is left between the stepped ore-settling platform and the left side wall of the transfer funnel.

[0006] Preferably, the cross-section of the transfer funnel is rectangular; the stepped ore-settling platform is arranged along the length direction of the transfer funnel.

[0007] Preferably, the upper end surface of the buffer platform is an inclined surface that is higher on the left and lower on the right.

[0008] Preferably, a gap is left between the buffer platform and the right side wall of the transfer funnel.

[0009] Preferably, the blanking end of the upstream conveyor belt is arranged above the main blanking channel; the feeding end of the downstream conveyor belt is arranged below the transfer funnel.

[0010] Preferably, the stepped ore-settling platform is composed of a plurality of L-shaped plates, and the L-shaped plates are detachably connected to each other.

[0011] Advantages of the present utility model:

[0012] By arranging the stepped ore-settling platform in the transfer funnel, the present utility model can buffer the ore with a large kinetic energy, reduce the ore speed, and further reduce the impact on the transfer funnel and the downstream conveyor belt, thereby avoiding or reducing the influence on the transfer funnel or the downstream conveyor belt caused by the ore impact;

[0013] The structure of the stepped ore-settling platform with a higher left side and a lower right side can solve the problem of the falling impact points of different particle sizes in the ore composition and prevent the ore from directly acting on the downstream conveyor belt.

[0014] By arranging a buffer platform on the right side of the stepped ore-settling platform, the present utility model can reduce the secondary buffering force of the ore falling from the stepped ore-settling platform, especially can buffer the ore with a large particle size (greater than 300 mm), and realize the protection of the downstream conveyor belt.

[0015] The present utility model designs the transfer funnel into a structure with a rectangular cross-section, so that while the stepped ore-settling platform has sufficient installation space in the transfer funnel, it can better adapt to the characteristic that the movement trajectory of the ore with a large kinetic energy moves towards the right, enabling the ore to effectively fall along the stepped ore-settling platform and decelerate.

[0016] The present utility model reserves a gap between the stepped ore-settling platform and the left side wall of the transfer funnel to form a main feeding channel, and arranges the discharging end of the upstream conveyor belt opposite to the main feeding channel and the downstream conveyor belt below the transfer funnel. During the ore conveying process, most of the ore will enter the downstream conveyor belt through the main feeding channel, which will not affect the normal conveying volume of the ore, and can buffer and decelerate the ore with a large kinetic energy, that is, solve the problem of the ore impacting the transfer funnel and the downstream conveyor belt without reducing the ore conveying volume.

Detailed implementation manner

[0022] In order to make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following will, in conjunction with the accompanying drawings, elaborate on the preferred embodiments of the present utility model for the convenience of those skilled in the art to understand.

[0023] In the description of the present utility model, unless otherwise specified, the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0024] In the description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection" and "provided with" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] As Figures 1-3 shown, the ore conveying structure includes an upstream conveyor belt 1, a transfer hopper 2 and a downstream conveyor belt 3. The transfer hopper 2 is arranged between the upstream conveyor belt 1 and the downstream conveyor belt 3, and the materials conveyed by the upstream conveyor belt 1 enter the downstream conveyor belt 3 after passing through the transfer hopper 2.

[0026] The present utility model is aimed at the conveying of ores that are not fully crushed after mining. Such ores have large fluctuations in density and water content, and a large particle size range. When the ores fall from the upstream conveyor belt 1 into the transfer hopper 2, their movement trajectories and speeds are quite different. Most of the ores will fall directly from the discharge end of the upstream conveyor belt 1, and some will continue to move forward along the upstream conveyor belt 1 and fall in a parabolic shape, hitting the wall of the transfer hopper 2, causing deformation or even damage to the transfer hopper 2. And the ores after hitting the transfer hopper 2, when still having relatively large kinetic energy, will rebound to the downstream conveyor belt 3 or fall into the area around the downstream conveyor belt 3, affecting the normal operation of the downstream conveyor belt 3 or posing a safety hazard of damaging the equipment or workers. The present utility model is provided with a stepped ore-settling platform 4 and a buffer platform 5 in the transfer hopper 2, which can effectively alleviate or solve this problem.

[0027] The cross-section of the transfer funnel 2 is rectangular. The stepped ore-settling platform 4 is arranged along the length direction of the transfer funnel 2, and a main discharging channel 6 is reserved between the left side and the transfer funnel 2. The stepped ore-settling platform 4 is higher on the left and lower on the right, and is composed of detachable L-shaped plates 7. One composition method of the stepped ore-settling platform 4 in this embodiment is listed as follows:

[0028] The stepped ore-settling platform 4 includes an L-shaped mother plate 41 at the rightmost side, a second L-shaped plate 42 adjacent to the L-shaped mother plate 41 and detachably connected to the L-shaped mother plate 41, and other L-shaped plates detachably connected to the L-shaped mother plate 41 and the second L-shaped plate 42. The specific connection method between each L-shaped plate is as follows: On the vertical plate and the horizontal plate of the L-shaped mother plate 41, multiple rows of bolt groups 46 composed of two rows of bolts are respectively arranged. The horizontal section of the second L-shaped plate 42 is on the top and the vertical section is on the bottom, and it is clamped by the bolt group 46; On the right end face of the vertical plate of the second L-shaped plate 42, multiple rows of bolt groups 46 composed of two rows of bolts are also arranged; The horizontal plate of the third L-shaped plate 43 is on the top and the vertical plate is on the bottom and is clamped by the bolt group 46; On the upper end face of the horizontal section of the third L-shaped plate 43, a bolt group 46 composed of two rows of bolts is also arranged; The horizontal plate of the fourth L-shaped plate 44 is on the top and the vertical plate is on the bottom, and is clamped by the bolt group 46; On the upper end face of the fourth L-shaped plate 44, a bolt group 46 composed of two rows of bolts is also arranged. The horizontal plate of the fifth L-shaped plate 45 is on the top and the vertical plate is on the bottom, and is clamped by the bolt group 46. When it needs to be disassembled, remove one row of bolts located outside the L-shaped plate, and the L-shaped plate can be removed.

[0029] The L-shaped mother plate 41 and the buffer platform 5 are respectively welded on the hopper wall of the transfer funnel 2, forming an integral structure with the transfer funnel 2.

[0030] Through the detachable connection between each L-shaped plate, the stepped ore-settling platform 4 with different total heights, different total lengths, different stepped heights, and different stepped lengths can be selected according to the mud content and moisture of the ore, so as to realize the reasonable stacking amount of ore materials on the ore-settling platform. If the length is too long, it is easy to cause the funnel to be blocked. If the length is too short, the ore will not be accumulated enough, and the protection effect on the downstream conveyor belt will be lost. According to the change of ore particle size, different ore-settling platform heights are selected to realize the buffering of different particle sizes on different steps.

[0031] A buffer platform 5 is arranged on the left side of the stepped ore-settling platform 4. The buffer platform 5 can block the ore falling from the stepped ore-settling platform 4, mainly aiming at blocking and buffering large-grained (greater than 300 mm) ore to prevent it from hitting the transfer funnel 2.

[0032] As a preferred solution, the upper end face of the buffer platform 5 is an inclined surface that is higher on the left and lower on the right, which is more conducive to alleviating the impact force of large-grained ore.

[0033] A gap is reserved between the stepped ore-settling platform 4 and the left side wall of the transfer funnel 2 to form a main feeding channel 6. The feeding end of the upstream conveyor belt 1 is arranged above the main feeding channel 6, and the feeding end of the downstream conveyor belt 3 is arranged below the transfer funnel 2. During the ore conveying process, most of the ore will enter the downstream conveyor belt 3 through the main feeding channel 6, which will not affect the normal conveying capacity of the ore, and can play a role in buffering and decelerating the ore with large kinetic energy. That is, without reducing the ore conveying capacity, the problem of the ore impacting the transfer funnel and the downstream conveyor belt is solved.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
